Visual COBOL uses different configuration files and variables. You need to review your existing ACUCOBOL-GT configuration to determine which settings are relevant for use and which settings have Visual COBOL equivalents.
For example, some configuration settings for handling Vision files can be set in the default File Handler in Visual COBOL.
Some ACU configuration variables are not necessary or applicable in Micro Focus COBOL (for example, PERFORM_STACK), and the functionality of others is covered by the Micro Focus COBOL compile and run-time options (for example, A_CHECKDIV).
